How to Help Birds When Insect Food Is Scarce

When natural insect populations drop—due to cold snaps, drought, or habitat loss—insect-eating birds struggle to find food. This guide explains practical ways to provide alternative nutrition and support birds through lean periods. You’ll learn what to offer, how to offer it safely, and what to avoid.

What You’ll Need

• Mealworms (dried or live)
• Suet cakes or suet dough (insect-based or plain)
• Bird-safe seed mix (sunflower hearts, nyjer, millet)
• Peanut butter (unsalted, no additives)
• Oats or whole-wheat flour (for homemade mixes)
• Shallow dishes or trays
• Clean water source (birdbath or shallow pan)
• Optional: bird feeder with mesh or tray design

Step-by-Step

1. Offer live or dried mealworms. Place them in a shallow dish or a feeder with a lip. Live mealworms are more attractive but dried ones are easier to store. Replenish daily, removing any uneaten worms after 24 hours to prevent spoilage.
2. Put out suet. Choose plain suet cakes or those with added insects. Hang them in a suet feeder or place on a flat tray. Suet provides high-energy fat that birds need, especially in cold weather.
3. Provide high-protein seed mixes. Sunflower hearts, nyjer, and millet are good options. Avoid mixes with fillers like red milo or wheat, which many birds ignore. Use a feeder with a tray to catch spills.
4. Make a simple insect-replacement mix. Combine 1 part peanut butter, 1 part oats, and 1 part cornmeal (or whole-wheat flour). Form into small balls or spread on a pinecone. This mimics the texture of insect masses and provides protein and fat.
5. Keep water available. Birds need water for drinking and bathing, especially when insects are scarce. Use a shallow birdbath with a rough surface and add a few stones for perching. Change water daily and prevent freezing in winter.
6. Plant insect-friendly plants. Even in a small garden, native plants like goldenrod, aster, and milkweed attract insects and provide natural food sources. Avoid pesticides that kill insects.
7. Leave leaf litter and brush piles. These areas harbor insects and spiders that birds can forage. Avoid raking every leaf or clearing all dead wood.
8. Monitor and adjust. Watch which foods are being eaten and adjust quantities. If mealworms go untouched, try a different feeder or placement. If suet disappears quickly, add more.

Common Mistakes

• Offering spoiled food. Damp or moldy seeds and suet can make birds sick. Check feeders daily and clean them with a mild bleach solution (1 part bleach to 9 parts water) every two weeks.
• Using salted or seasoned foods. Salt, spices, and artificial additives are harmful to birds. Stick to plain, unsalted peanut butter and natural suet.
• Placing feeders too close to windows. Birds can collide with glass. Position feeders within 3 feet of windows or more than 30 feet away to reduce risk.
• Forgetting about predators. Feeders at ground level can attract cats. Place feeders high enough (5-6 feet) and use baffles to deter squirrels and raccoons.
• Stopping suddenly. If birds have come to rely on your feeders, a sudden stop can leave them without a food source. Reduce gradually if you need to stop.

Tips

• Start with small amounts and increase as birds discover the food.
• Use a mix of feeder types: tube feeders for small seeds, tray feeders for mealworms and suet.
• Place feeders in a sheltered spot, out of strong wind and rain.
• Clean feeders regularly to prevent disease transmission.
• Consider a heated birdbath in winter to keep water liquid.
• Observe from a distance to avoid disturbing feeding birds.

Troubleshooting

Birds aren’t visiting. It may take a few days for birds to find new food. Ensure feeders are visible and near natural cover like trees or shrubs. If no birds come after a week, try moving the feeder to a different location.

Food is getting wet or moldy. Use a feeder with a roof or place food in a sheltered area. Only put out as much as birds will eat in a day or two.

Squirrels are eating everything. Use a squirrel-proof feeder or add a baffle. Offer squirrel-resistant foods like nyjer seed, which squirrels often ignore.

Mealworms are drying out or dying. Live mealworms need a cool, dry place and a small piece of carrot or potato for moisture. Dried mealworms can be rehydrated by soaking in warm water for 10 minutes.

Birds seem to prefer one food over another. That’s normal. Offer a variety and let the birds choose. You can gradually reduce less popular items.

Frequently Asked Questions

Q: Can I feed birds bread when insects are scarce? A: Bread offers little nutritional value and can fill birds up without providing essential protein and fat. It’s better to offer mealworms, suet, or high-protein seeds.

Q: Are dried mealworms as good as live ones? A: Dried mealworms are convenient and still provide protein, but they lack the moisture of live insects. Rehydrate them before offering to increase appeal.

Q: How often should I clean feeders? A: Clean feeders every two weeks, or more often if they become visibly dirty or after heavy rain. Use a diluted bleach solution and rinse thoroughly.

Q: Will feeding birds make them dependent on me? A: Birds will still forage naturally, but they may visit your feeder regularly as a reliable food source. That’s fine, but avoid making them entirely dependent by offering only a portion of their daily needs.

Q: What should I do if I find a sick bird near the feeder? A: Remove the feeder and clean it thoroughly. Stop feeding for a few days to encourage birds to disperse. Contact a local wildlife rehabilitator if the bird appears injured or severely ill.

Q: Can I use kitchen scraps like fruit or vegetables? A: Some fruits (apples, berries) and vegetables (corn, peas) are safe, but avoid processed foods, salty snacks, and anything with sugar or artificial sweeteners. Offer scraps in small amounts and remove uneaten portions.
